Wisdom tooth extraction is prescribed in certain conditions such as partial tooth eruption, incorrect tooth position, crowding, tooth damage, etc. The extraction of the affected wisdom tooth or teeth helps reduce the risk of future oral complications such as infection or periodontal diseases in surrounding teeth or gums.
In typical situations, once the tooth is extracted, a blood clot is formed at the site of tooth extraction. This clot acts as a protective layer over the underlying nerve endings and bone. It also provides the base for the growth of new bone and soft tissue. However, when this blood clot fails to develop, is dislodged or gets dissolved due to any reason before the site has healed, a dry socket is formed. Alveolar osteitis or dry socket is a common oral complication that can occur at the site of tooth extraction after the surgery.
